Yes. Put them through an extensive workout and get them to drink protein shakes. Always wear tight but comfortable clothing and bring a towel to clean the machinery. I suggest putting on the some 80's tunes to work out to.

Don't grip to hard, move up and down slowly at first and gradually work your way to playing full speed, keep that up and down motion (scales are great practice!), and if need be add some lubricant to make it easier and feel nicer

You'll get used to it, but be prepared to take a step back and slow down everything you were able to play, for a while. I switched to .11's-.13's for all my guitars (acoustics and electrics), and I haven't been happier. They sound good, they feel good... It just takes a while to build up the strength to be able to bend them effectively, and get good strong callouses.
